Olivia Newton-John as Sandy in Grease is an absolute icon, and her transformation at the end of the movie is unforgettable! Did you know Grease was the highest-grossing musical of the 20th century? Its popularity has led to endless Halloween costume inspiration, and Sandy’s “bad girl” look is one of the easiest to pull off.

To recreate this look, all you need is:

1. Black Leather jacket. Doesn’t everyone have some kind of black leather, fitted jacket these days?

2. Leather Leggings. If you don’t have these, you can find faux ones just about anywhere these days for under $30 or go with my favorites (and a bit pricier) by Spanx that will get more wear than you expected!.

3. Fitted black top. It doesn’t need to be cropped. Just make sure it’s fitted and low cut if it’s not.

4. Heels. Any color will do and they don’t need to be sky high.

5. Big, Curly hair. If you don’t have blonde hair, wigs are easy to come by. Otherwise put those hot rollers in and then tease the crap out of it.

Voila! You’re ready to channel your inner Sandy!
